Briefly, this error occurs when Elasticsearch encounters non-double values in fields that are expected to be double. This could be due to incorrect data types being used or invalid data being inputted. To resolve this issue, you can: 1) Check the data being inputted and ensure it is in the correct double format. 2) Validate your data before indexing to prevent invalid data from being inserted. 3) Modify your mapping to match the data type of the field. Remember, changing the mapping requires reindexing.

Log Context
Log “[{}] and [{}] must be valid double values” class name is GeoUtils.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :
throw new ElasticsearchParseException("field must be either lat/lon or geohash");
} else {
return point.parseGeoHash(geohash; effectivePoint);
}
} else if (numberFormatException != null) {
throw new ElasticsearchParseException("[{}] and [{}] must be valid double values"; numberFormatException; LATITUDE;
LONGITUDE);
} else if (Double.isNaN(lat)) {
throw new ElasticsearchParseException("field [{}] missing"; LATITUDE);
} else if (Double.isNaN(lon)) {
throw new ElasticsearchParseException("field [{}] missing"; LONGITUDE);
